I really think this should be left up to the judge.
One extreme a woman marries at 18 like I did, avoids college and career building to focus on husband’s education, home keeping and career, and gets dumped or cheated on or serious abused at 45 you know what, lifetime alimony.
Other extreme a well educated career gal marries at 30 loses no income gets bored at 35 and leaves the man - no alimony.
It is not just to take a woman’s prime educational, childbearing, and career building years and then dump her. She should get life time alimony of a reasonable amount if she was gutted. There is no emotional, career, or financial rebuild at the point to be made.
Even in your example - which is an extreme one [and proving that abuse would be tough] - paying alimony after early retirement age of 62 would be nuts (or 17 years in this example, I still don’t see more than half the # of years you are married as worst case scenario of reasonable, which is 13.5). You’ll get half the assets at divorce, plus a good chunk of his income in his most likely normal years, plus can work to make money yourself now. Lifetime alimony is nuts, especially if there were significant assets to split, and you’ll already be eligible for half his SS.
